Only formatting and removal of not needed comments versus previous one. Previous one was applied on 7.4 for cygwin binary package without any build problem

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47030 --- Comment #9 from marco atzeri --- It seems the patch works, just not as I was expecting. The code allows to export the variables in the common block -- $ cat mydll-3.f90 ! mydll.f90 -- ! Simple library (to be compiled and linked as DLL/SO) ! subroutine print real :: x common /mydata/ x !GCC$ attributes dllexport :: x write(*,*) 'X = ', x end subroutine print --- With gcc-7.3.0 the test case fails as usual X =0. In program: X =1. with the patch it works. X =1. In program: X =1.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47030 --- Comment #7 from marco atzeri --- I am trying to update the draft patch of Tobias to gcc-7.3.0 the current gcc on cygwin. The attached patch builds but does not solve the problem of !GCC$ attributes dllexport :: /mydata/ 1 Error: Invalid character in name at (1) nor !GCC$ attributes dllexport :: mydata 1 Warning: Unused variable ‘mydata’ declared at (1) [-Wunused-variable] I see two possibilities: 1) the original path was missing the portion of interpreting "/mydata/" as valid symbol 2) my guess of "com->head->attr" for original "common_sym->attr" is wrong and eventually both applies. Any suggestion for solving "Error: Invalid character in name at (1)" ?

Compiling the second test gives f951: warning: 'dllexport' attribute directive ignored [-Wattributes] for 4.8 and 4.9 and an ICE for 5.2.0 and 6.0 (pr68040). I don't get any warning for the third test for 4.8 up to trunk (6.0).

Which makes sense, because a common block and a local entity can have the same name (with certain restrictions; see 16.3.1 and 16.3.2 in f2008). Looking at the syntax of the Intel Fortran compiler, the name of the common block has to be between slashes: !DEC$ ATTRIBUTES DLLEXPORT :: /X/ http://software.intel.com/sites/products/documentation/hpc/compilerpro/en-us/fortran/win/compiler_f/bldaps_for/win/bldaps_share_datadlls.htm Trying this with gfortran gives an error: !GCC$ attributes dllexport :: /mydata/ 1 Error: Invalid character in name at (1) P.s.: !- module m real :: x common /mydata/ x !GCC$ attributes dllexport :: mydata end module !- I get the warning: f951: warning: ‘dllexport’ attribute directive ignored [-Wattributes] I get an error (I'm using MinGW GCC 4.6.2): m.f90:5:0: error: external linkage required for symbol 'mydata' because of 'dlle xport' attribute
